PIANO-TRUCK.

SPECIFICATION forming part of Letters Patent No. 616,972, dated January3, 1899.

. Application filed February 11.1898. Serial No. 669,961. (No model.)

T0 all whom it may concern:

Be it known that I, PHILO 1V. RAYNOR, a citizen of the United States,and a resident of Findlay, in the county of Hancock and State of Ohio,have invented certain new and useful Improvements in Trucks for MovingPianos; and I do hereby declare that the following is a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification..

Myinvention relates to trucks or apparatus for moving pianos 3 and itsobject is to provide an improved construction of the same which shall beeasily connected with a piano and be loaded in a wagon fortransportation or the piano be moved from place to place by hand andwhen not in use can be readily cary in detail I would state that thereare two trucks bars, but when in use to be extended at right angles tosaid bars, being held in said position by chains 5, secured thereto andto said bars. Secured to said bars at the upper ends is a board G,adapted to rest against the end of a piano and provided with a cushion 7at one end to prevent injury to the piano. Oonnected with the cushions 7is a strap fgwhich is lined with one or more sheets of duck or the pianoto the trucks.

Adown therein.

other suitable material. This strap passes over the front of the piano just above the keyboard and serves to prevent injury to the piano whilebeing carried through doorways. The numeral 8 designates lugs secured tosaid bars, with which are connected straps 9, extending around the frontand back of the piano. There is also a strap 10 connected with rod 3,which extends over the top of the piano. The object of this strap is tosecurely hold Secured to the lower ends of said bars 1 is a board 12,the inner side of which, as well as the board 6, is provided with alining or covering of some soft material, such as cloth or felt, forpreventing` marring or injuring the piano. Hinged to said bars by hinges13 is a movable U or angular shaped frame 14, comprising the horizontalrod 14 and the arms 14,b at right angles thereto, to the' ends of whicharms is journaled a roller 15, having metal bands 16 at the ends and thecenter provided with a ratchet-Wheel 17. Engaging with the ratchetwheelis one end of a tongue or pawl 18, the other end of which is journaledto the horizontal portion ofthe frame 14.

Secured to each of the arms 14h is a screweye 19, in which eye is journaled a horizontal rod 20, formed at the center with a crank oreccentric 21, which is located behind the pawl. In front of said pawl isa loop 28, provided with eyes 24. at the ends, which engage with thesaid crank or eccentric. One end of rod 2O is lformed with a crank 25,by which to rotate the same. rIhe arms 141 of the said frame are formedwith slots 26, with which engage hooked lugs 27, secured to the bars 1.It will be noted that the hinges or bearings 13 of the frame 14 consistof plates or oifsets 28, so that the arm lei of the frame can move upand The object of this construction is that when the hooked lugs arepassed through the slots 26 the frame can be raised slightly, so as toallow the ends of the lugs to engage over the lower ends of the slotsand hold the frame securely to the bars 1. For the purpose of holdingthe said frame in such elevated position I provide a lever 29, pivotedto the said board,.having a pin 30, which engages with the arm 14. ofthe frame. When this lever is turned to a perpendicular position, saidpin will lock or hold it in place.

IOO

As before stated, there is one of the trucks or devices described ateach end of the piano, and in use the bent lower en ds of the bar I areengaged under the ends of the piano, the lugs being disengaged from theslot 2G and the frame 14 thrown outward, as seen in Fig. 2, and thepiano secured to the truck by the straps. The eccentric and loop arethen turned, so that the tongue or pawl 1S will be thrown intoengagement with the ratchetwheel of the roller, thus holding the latteragainst rotation. The ends of the piano are then slightly raised by thehandles and the frame 14. pushed inward, so that the piano will besupported by the rollers, the weight of the piano causing said frame tomove npward, so that the lugs 27 will engage with the lower ends of theslots in the arms 14, and thus hold the frame against the side bars l.The lever 26 is then turned to a perpendicular position, so that its pinwill engage under the rod let:L and hold the frame in its elevatedposition. The rod 20 is then turned, so that the eccentric and loop willthrow the pawl out of engagement with the ratchet-wheel to allow theroller to rotate and the trucks be moved over a door or pavement. Thepiano can be lifted into and out of a wagon bythe handles.

IVhen the trucks are removed from the piano, they may be folded so as tooccupy but little room in transportation.

Having thus fully described my invention, what I claim isl. In a truckfor moving pianos, the combination with the bars connected together atthe lower ends by a transverse board provided with a cushion andconnected at the upper ends by a transverse board provided with acushion at the front end and the lower ends of said bars turned inwardlyat right angles, of the handles pivoted to the upper ends of said barsand the straps, substantially as described.

2. In an apparatus for moving pianos, the combination with the barshaving the lower ends bent approximately at right angles, thepivoted'handles at the upper ends of said bars and the straps, of thepivoted frame at the lower ends of said bars, the roller journaledthereto, and means for locking said roller against rotation,substantially as described.

3. In an apparatus for moving pianos, the combination with the barshaving their lower ends bent approximately at right angles, and thepivoted handles at the upper ends of said bars, of the pivotedvertically movable frame, the hooked lugs adapted to project throughslots in the side arms of saidframe, the roller journaled to the ends ofsaid arms, and the pivoted lever provided with a pin engaging with saidframe, substantially as described.

4. In an apparatus for moving pianos, the combination with the barshaving their lower ends bent approximately at right angles and thepivoted or hinged handles at the upper ends of said bars, of the pivotedverticallymovable frame, the hooked lugs adapted to project throughslots in the side arms of said frame, the pivoted lever having a pinengaging with the horizontal arm of the frame, the roller journaled tothe frame, the ratchetwheel, the transverse rotatable rod and theeccentric and loop, substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
